Modular Street & Race Headers For The 992 GT3 & GT3 RS
Fabspeed’s RENNKRAFT® (“Race Power”) modular headers are the world’s first patented dual-purpose system for the 992 GT3 / GT3 RS. A V-band quick-release lets you swap between street-legal HJS-imported sport cats and track-only QUICKTRACK™ cat-bypass pipes in minutes — one set of headers, two cars in one.
Why RENNKRAFT®
Two Cars In One Header
The patented V-band quick-release joint between the header collector and the catalytic section means swapping from street-legal HJS sport cats to QUICKTRACK™ cat-bypass pipes is a 10-minute job. No re-tune, no re-mount, no header replacement.
200-Cell Euro 6 Homologated Cats
HJS Emitec Germany 200-cell Euro 6 homologated tri-metallic catalytic converters — imported direct from HJS. Fabspeed is HJS’s exclusive North American distributor. Anyone selling HJS cats not sourced through Fabspeed is selling grey-market or counterfeit.
3D Laser-Scanned, Dyno-Tuned
Fabspeed was the world’s first company to 3D laser-scan, design, patent, and dyno-develop these headers in partnership with HJS Germany and noted Porsche engine builders. Optimal length and diameter validated against a stock 992 GT3 baseline.

- 3D laser-scanned directly off the OEM 4.0L flat-six for precision fitment

Compliance & Compatibility
CARB / Emissions: The Sport Cats configuration uses Euro 6 homologated catalytic converters. The Cat Bypass Pipes configuration is for closed-course competition only and is not legal for street use in jurisdictions with monitored GPF systems — it will set a check-engine light unless used with a tune or simulator.
Fitment: All Porsche 992 GT3 and 992 GT3 RS models worldwide. Note: EU-spec cars with GPF will throw a CEL on the cat-bypass pipes unless paired with a tune or O2 simulator.
HJS authenticity: Fabspeed Motorsport USA has been HJS’s exclusive North American importer for 20+ years. Any HJS-equipped product not sourced through Fabspeed is grey-market or counterfeit. FFP is an authorized Fabspeed dealer — your product ships from Fabspeed direct.
